Flood planning in Inner West — common questions
Is my Inner West property in a flood planning area?
Parts of the Inner West are in flood planning areas, particularly near the Cooks River, Hawthorne Canal, and creek lines through Marrickville, Leichhardt, and Ashfield. Use the checker above to see if your specific address is within the mapped flood planning area.
What are the main flood risks in the Inner West?
The Cooks River and its tributaries, Hawthorne Canal, and local overland flow paths are the primary flood sources. The Inner West has experienced significant flash flooding in recent years, particularly in low-lying areas near creek lines.
Does flood risk affect granny flat eligibility in the Inner West?
Yes. Under SEPP Housing 2021, properties on flood control lots cannot use the complying development (CDC) pathway for secondary dwellings. A DA with flood risk assessment is required instead.
How do I get the official flood status for an Inner West property?
A Section 10.7 Planning Certificate from Inner West Council is the authoritative source. This discloses statutory flood information and is required for conveyancing.
Need the full planning picture?
Flood is one layer. A full report covers heritage, CDC eligibility, DCP setbacks, and nearby DA activity.
